为什么我看不到fclose

低级错误

还是不行啊

#include<stdio.h>

int
main(void)
{
      int i, j;
      double a[2][3]={{1.0,2.0,3.0},{4.0,5.0,6.0}};
      double c[2][3];
      FILE *fp1,*fp2;


      fp1=fopen("d:\\output.txt","wb");

      if(fp1==NULL)
      {
            printf("cann't open this file\n");
            return 0;
      }
      for(i=0;i<2;i++)
      {
            for(j=0;j<3;j++)
                  fwrite(&a[i][j],sizeof(double),1 ,fp1);
      }

      fclose(fp1);

      if((fp2=fopen("d:\\output.txt","rb"))==NULL)
      {
            printf("can't open file!");
            exit(0);
      }
      for(i=0;i<2;i++)
            for(j=0;j<3;j++)
            {
                  fread(&c[i][j],sizeof(double),1,fp2);
                  printf("%f ",c[i][j]);
            }
      fclose(fp2);
      getch();
      return 0;
}
